Overview
The E300™ Electronic Overload Relay is a microprocessor-based electronic
overload relay designed to protect three-phase or single-phase AC electric
induction motors rated from 0.5…65,000 A. Its modular design, communication
options, diagnostic information, simplified wiring, and integration into Logix
makes this the ideal overload for motor control applications in an automation
system. The E300 Electronic Overload Relay provides flexibility, reduces
engineering time, and maximizes uptime for important motor starter
applications.
Modular Design
Users can select the specific options needed for their motor starter application.
The E300 Electronic Overload Relay consists of three modules: sensing, control
and communications. Users have choices in each of the three with additional
accessories to tailor the electronic motor overload for their application’s exact
needs.
Users can select from multiple communication options which integrate with
Logix based control systems. Developers can easily add the E300 Electronic
Overload Relay to Logix based control systems using Integrated Architecture
tools such as Add-on Profiles, Add-on Instructions, and Faceplates.

Control Module
Figure 2 - Control Module
The control module is the heart of the E300 Electronic Overload Relay and can
attach to any sensing module. The control module performs all of the protection
and motor control algorithms and contains the native I/O for the system. The
control module has two varieties:
• I/O only
• I/O and prote
ction (PTC & External Ground Fault Current Sensing)
The control module is offered in three control voltages:
• 110…120V AC, 50/60Hz
• 220…240V AC, 50/60Hz
• 24V D
Ext

The E300 Electronic Overload Relay supports two network protocols:
• EtherNet/IP
• DeviceNet
The
E300 EtherNet/IP Communication Module has two RJ-45 connectors that
funct
ion as a switch. Users can daisy chain multiple E300 Electronic Overload
Relays with Ethernet cable, and the module supports a Device Level Ring (DLR).
Optional Add-On Modules
Optional Expansion I/O
The E300 Electronic Overload Relay allows the user to add additional digital and
analog I/O to the system via the E300 Electronic Overload Relay Expansion Bus
if the native I/O count is not sufficient for the application on the base relay. Users
can add up to four additional Digital I/O Expansion Modules that have 4 inputs
(120V AC, 240V AC, or 24V DC) and 2 relay outputs.
Users can also add up to four additional Analog I/O Expansion Modules, which
have three independent universal analog inputs and one isolated analog output.
The independent universal analog inputs can accept the following signals:
• 4…20 m

The E300 Electronic Overload Relay offers the user the capability to add one
operator interface to the Expansion Bus. There are two types of operator stations
that the user can chose from: control station or a diagnostic station. Both types of
operator stations mount into a standard 22 mm push button knockout, and they
provides diagnostic LEDs which allow the user to view the status of the E300
Electronic Overload Relay from the outside of an electrical enclosure. Both
operator stations provide push buttons which can be used for motor control
logic, and they both can be used to upload and download parameter
configuration data from the base relay. The diagnostic station contains a display
and navigation buttons that allows the user to view and edit parameters in the
base relay.
Optional Expansion Bus Power Supply
Figure 5 - Expansion Bus Power Supply
The E300 Electronic Overload Relay expansion bus provides enough current to
operate a system that has (1) Digital Expansion Module and (1) Operator
Station. An E300 Electronic Overload Relay system that contains more
expansion modules will need supplemental current for the Expansion Bus. The
E300 Electronic Overload Relay offers users two types of Expansion Bus Power
Supplies: AC (110…240V AC, 50/60 Hz) and DC (24V DC). One Expansion
Bus Power Supply supplies enough current for a fully loaded E300 Electronic

derating. In addition to the specific precautions listed throughout this manual,
the following general statements must be observed.
ATT EN TI ON : The E300 Electronic Overload Relay contains electrostatic
discharge (ESD) sensitive parts and assemblies. Status control precautions are
required when installing, testing, servicing, or repairing this assembly.
Component damage may result if ESD control procedures are not followed. If
you are not familiar with static control procedures, refer to Allen-Bradley
publication 8000-SB001_-en-p, “Guarding Against Electrostatic Damage”, or
any other applicable ESD protection handbook.
ATT EN TI ON : An incorrectly applied or installed E300 Electronic Overload Relay
can result in damage to the components or reduction in product life. Wiring or
application errors (e.g., incorrectly figuring the FLA setting, supplying incorrect
or inadequate supply voltage, connecting an external supply voltage to the
thermistor terminals, or operating or storing in excessive ambient
temperatures) may result in malfunction of the E300 Electronic Overload Relay.
for the appropriate temperature
Base Relay Assembly
ATT EN TI ON : Only personnel familiar with the E300 Electronic Overload Relay
and associated machinery should plan to install, start up, and maintain the
system. Failure to comply may result in personal injury or equipment damage.
ATT EN TI ON : The purpose of this user manual is to serve as a guide for proper
installation. The National Electrical Code (NEC) and any other governing
regional or local code will overrule this information. Rockwell Automation
cannot assume responsibility for the compliance or proper installation of the
Electronic Overload Relay or associated equipment. A hazard of personal

peripherals will require an Expansion Bus Power Supply which connects as the
first module on the Expansion Bus.
Users will set the address dial of the Expansion Digital Module to a unique digital
module address number (1-4). If the Expansion Digital Module is the last device
on the Expansion Bus, set the address to the address value that enables in the
internal terminating resistor (1T-4T). A power cycle is required when changes
are made to the address dial.
Users will set the address dial of the Expansion Analog Module to a unique
analog module address number (1-4). If the Expansion Analog Module is the last
device on the Expansion Bus, set the address to the address value that enables in

changes are made to the address dial.
Users will connect the E300 Base Relay to the Expansion Module’s Input Port
using the supplied Expansion Bus cable. Users will add the next Expansion
Module by connecting the supplied Expansion Bus cable to the Output Port of
the previous Expansion Module and into the Input Port of the additional
Expansion Module. The Operator Stations is the last device on the E300
Expansion Bus; it only has an Input Port with an internal Expansion Bus
terminating resistor.
If the user supplied Expansion Bus cable is not long enough for the installation,
